Create a design with a unique pattern by adding this 13mm round paua ruby cabochon. The cabochon features a shiny marbled red and black center. The makers of the cabochon achieved this effect by layered a paua shell between a black resin back and a transparent red curved resin front. Use this cabochon for craft projects, earrings or fashion accessories. Paua shell comes from New Zealand, where its coloring and iridescent properties have made it popular with tourists. Because the shells are natural, each cabochon will have a different pattern. Feel free to browse for other cabochons.
